Description

Technical Field

[0001] This invention belongs to the field of ship auxiliary equipment technology, specifically referring to a ship rescue device for people falling into the water. Background Technology

[0002] During maritime navigation or transportation, the ability to quickly and safely rescue those who have fallen overboard is directly related to their safety and the operational safety of the vessel. Currently, ships are generally equipped with lifeboats as the main life-saving equipment for dealing with people falling overboard. Their main function is to transport rescuers to the vicinity of the person who has fallen overboard, transfer the person to the lifeboat, and then safely return them to the mother ship or shore.

[0003] Existing lifeboats typically require a davit to lift them from the ship's deck and deploy them into the water. A Chinese invention patent, CN113492949A, discloses a lifeboat lifting device for ship rescue. A hydraulic cylinder pushes a support rod to rotate via a push rod, which in turn rotates a rotating rod. Two rotating rods of equal length are rotatably connected to the lower surface of the lifting platform, forming a parallelogram structure. This allows the lifting platform to descend slowly and parallel, ensuring the rope can smoothly lower the lifeboat into the water and preventing the lifeboat from tilting. However, the entire lifting device is biased to one side of the ship. When lifting the lifeboat and the person in the water, it is difficult to precisely control the ship's center of gravity, which can easily lead to the ship capsizing.

[0004] Therefore, there is an urgent need for a new type of ship rescue device for people falling into the water to solve the above-mentioned defects. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a ship rescue device for personnel falling into the water. When the main hull approaches the person in the water, a rotating motor drives the rotating frame to rotate 90 degrees. Simultaneously, a hydraulic push rod is activated, pushing the rotating frame downwards to a suitable angle, submerging its lower end in the water. At this point, a winding motor starts, driving a winding roller to rotate, releasing the traction cable from the roller. This allows the lifeboat to slide along a limiting groove towards the water surface until a limiting ball disengages from the groove, releasing the lifeboat onto the water. After the person in the water enters the lifeboat, the winding roller rewinds the traction cable, returning the lifeboat to the limiting groove. The hydraulic push rod then drives the rotating frame back to a horizontal position, while the rotating motor drives the frame to rotate 90 degrees. The person in the water then enters the main hull from the lifeboat, achieving a safe rescue. This method is safer and more stable than the traditional method of releasing lifeboats via a hoisting device, effectively solving the technical problems mentioned in the background section.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: The present invention provides a ship rescue device for personnel falling into the water, comprising a main hull, with symmetrical adjustment mechanisms provided on the upper edges of the left and right ends of the main hull, and a lifeboat movably mounted above the adjustment mechanisms. Inflatable floats are arrayed along the length of the main hull on the sidewalls of the left and right ends of the main hull, and adjustment grooves are fixedly provided on the upper edges of the left and right ends of the main hull. The adjustment mechanisms are slidably arranged along the length of the adjustment grooves. The adjustment mechanisms include a moving block, a rotating disk, a rotating frame, and a hydraulic push rod. The moving block is slidably mounted within the adjustment groove, and a support plate is fixedly mounted on the moving block. The support plate is slidably mounted on the upper wall of the adjustment groove. The rotating disk is horizontally rotatably mounted on the upper wall of the support plate. The rotating frame is vertically rotatably mounted at the end of the rotating disk. The end of the hydraulic push rod is rotatably connected to the side wall of the rotating disk, and the output end of the hydraulic push rod is rotatably connected to the end of the rotating frame away from the rotating disk.

[0007] Furthermore, roller frames are symmetrically fixed on the upper wall of the rotating frame near the rotating disk. Take-up rollers are rotatably connected to the roller frames, and a traction cable is wound around each take-up roller. One end of the traction cable is fixed to the side wall of the take-up roller. Limiting grooves are symmetrically fixed on the upper wall of the rotating frame. The lifeboat is slidably positioned on the upper wall of the limiting grooves. Limiting rods are symmetrically fixed at both ends of the lower wall of the lifeboat, and limiting balls are fixed at the lower ends of the limiting rods. The other end of the traction cable passes through the interior of the limiting groove and connects to the rear limiting ball. The diameter of the traction cable is larger than the width of the limiting groove opening. When the lifeboat is located on the upper wall of the limiting groove, the limiting ball slides within the limiting groove, and the limiting rod slides within the opening of the limiting groove.

[0008] Furthermore, a connecting shaft is fixedly connected between the end faces of the take-up rollers, and a take-up motor is fixedly installed on the side wall of one side of the roller frame. The output end of the take-up motor is connected to the center of the end face of the take-up roller.

[0009] Furthermore, a rotating motor is fixedly installed on the upper wall of the support plate, the output end of the rotating motor is connected to the lower wall of the rotating disk, a rotating sleeve is fixedly installed symmetrically on the left and right ends of the rotating disk, and a rotating shaft is fixedly installed symmetrically on the left and right ends of the rotating frame near the rotating disk, and the rotating shaft is rotatably connected to the rotating sleeve.

[0010] Furthermore, an adjusting threaded rod is rotatably provided inside the adjusting groove, and a threaded rod motor is fixedly provided at the end of the adjusting groove. The output end of the threaded rod motor is connected to the end of the adjusting threaded rod.

[0011] Furthermore, a support block is fixedly provided at one end of the upper wall of the adjustment groove. When the rotating frame is parallel to the adjustment groove, the lower wall of the rotating frame contacts the support block.

[0012] Furthermore, air supply pipes are arranged in an array along the length of the main hull at the lower ends of the left and right side walls, and the inflatable floats are respectively connected to the air supply pipes.

[0013] Furthermore, a power propeller is rotatably mounted on the lower rear end of the main hull, and a stern rudder is mounted on the rear side wall of the main hull, with the stern rudder located behind the power propeller.

[0014] Furthermore, a control panel is fixedly provided at the front end of the main hull, and a control mechanism is fixedly provided at the rear end of the main hull. The control mechanism includes a main controller, an air pump, a rudder, and a drive motor. The air supply pipes are respectively connected to the output end of the air pump, the rudder stock of the stern rudder is connected to the output end of the rudder, and the shaft of the power propeller is connected to the output end of the drive motor.

[0015] Furthermore, the threaded rod motor, control panel, air pump, servo motor, drive motor, rotation motor, winding motor, and hydraulic push rod are all electrically connected to the main controller.

[0016] Furthermore, the main controller adopts an Omron CS1W-CT021 PLC controller.

[0017] The beneficial effects achieved by the present invention using the above structure are as follows: Once the main hull approaches the person in the water, the rotating motor will drive the rotating frame to rotate 90 degrees. At the same time, the hydraulic push rod will activate and push the rotating frame downward to a suitable angle, so that the lower end of the rotating frame is submerged in the water. At this time, the winding motor will activate and drive the winding roller to rotate. The traction cable will be released from the winding roller, allowing the lifeboat to slide along the limiting groove towards the water surface until the limiting ball disengages from the limiting groove. The lifeboat will then be released onto the water surface. After the person in the water enters the lifeboat, the winding roller will rewind the traction cable, allowing the lifeboat to return to the limiting groove. The hydraulic push rod will drive the rotating frame to rotate back to the horizontal position, and the rotating motor will drive the rotating frame to rotate 90 degrees, making it easier for the person in the water to enter the main hull from the lifeboat. This method is safer and more stable than the traditional method of releasing lifeboats through a hoisting device. When transporting people who have fallen into the water by lifeboat, the air pump can be controlled by the control panel to inflate the inflatable floats through the air supply pipes, increasing the buoyancy of the inflatable floats and thus further improving the stability of both sides of the main hull.

[0024] The threaded rod motor 112, control panel 14, air pump, servo motor, drive motor, rotation motor 212, winding motor 2323 and hydraulic push rod 24 are electrically connected to the main controller.

[0025] Working principle and workflow: In its initial state, the ship's lifesaving equipment is in Figure 1In the indicated state, the operator controls the main hull 1 to travel on the water surface via the control panel 14. The rudder and drive motor in the control mechanism 13 control the stern rudder 18 and the power propeller 17, respectively. The power propeller 17 provides forward propulsion, and the stern rudder 18 adjusts the direction of travel of the main hull 1. The stern rudder 18 and the power propeller 17 are existing technologies, and their specific structures and operating principles will not be described in detail here. After the main hull 1 approaches the person who has fallen into the water, the operator controls the adjustment mechanism 2 to unfold via the control panel 14. The control panel 14 sends a command to the main controller. After receiving the command, the main controller performs automated control of the various mechanisms within the device. First, the main controller starts the rotating motor 21. 2. The rotating motor 212 drives the rotating frame 23 to rotate 90 degrees. At the same time, the hydraulic push rod 24 is activated, pushing the rotating frame 23 downward to a suitable angle, so that the lower end of the rotating frame 23 is submerged in the water. At this time, the winding motor 2323 is activated and drives the winding roller 2321 to rotate. The traction cable 25 is released from the winding roller 2321. Due to gravity, the lifeboat 3 slides downward along the length of the rotating frame 23. The limiting ball 32 slides in the limiting groove 231, and the limiting rod 31 slides in the opening of the limiting groove 231, thereby limiting the lifeboat 3 to slide towards the water surface along the length of the limiting groove 231 until the limiting ball 32 disengages from the limiting groove 231. The lifeboat 3 is then released onto the water surface. Figure 2 and Figure 3 The state shown; After the person who fell into the water enters lifeboat 3, the operator can control the air pump through the air supply pipe 15 to inflate the inflatable float 4 via the control panel 14, increasing the buoyancy of the inflatable float 4 and thus further improving the stability of both sides of the main hull 1. The operator then controls the winding motor 2323 to start via the control panel 14. The winding motor 2323 drives the winding roller 2321 to rotate, and the winding roller 2321 rewinds the towing cable 25. Because the diameter of the towing cable 25 is larger than the width of the groove of the limiting groove 231, the towing cable 25 will not come off the groove of the limiting groove 231 when it is wound back onto the winding roller 2321. The lifeboat 3 is towed close to the rotating frame 23, and the limiting ball 32 is... Pulled by the traction cable 25, the lifeboat 3 re-engages into the limiting groove 231. As the traction cable 25 continuously rewinds and retracts the rewind roller 2321, the lifeboat 3 returns to the limiting groove 231 under the constraint of the limiting ball 32. Under the automatic control of the main controller, the hydraulic push rod 24 automatically drives the rotating frame 23 to rotate back to the horizontal position. At the same time, the rotating motor 212, under the automatic control of the main controller, drives the rotating frame 23 to rotate 90 degrees, so that the lifeboat 3 is parallel to the main hull 1. At this time, the lower wall of the rotating frame 23 contacts the support block 12, which supports the rotating frame 23 and ensures the stability of the rotating frame 23 and the lifeboat 3. The entire device returns to its original position. Figure 1As shown, the person who fell into the water enters the main hull 1 from the lifeboat 3, achieving a safe rescue of the person who fell into the water. This method is safer and more stable than the traditional method of releasing the lifeboat 3 through a hoisting device.
